Ditto is capable of copying an enemy’s genetic code to instantly transform itself into an exact duplicate of anything or anyone. In “Ditto’s Mysterious Mansion” Ash and friends meet Duplica, a Pokémon trainer trying to fix up her House of Imitae. The house’s main attraction is Duplica’s Ditto — even though it has trouble completing its transformations. Team Rocket then steals Ditto and threatens it until its transformations are perfect.
